Simplify the expressions. 3/2 − 1/2 a+ 2/3 a+ 3/2

Step-by-step explanation:

We have been given an expression and we are asked to simplify our given expression.

First of all let us combine like terms.

Now let us have a common denominator for the constant terms of a.

Now let us simplify the numerators.

Let us divide 6 by 2.

Therefore, our expression simplifies to .

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
